The 1977 All-Ireland Senior Football Championship final was the ninetieth All-Ireland Final and the deciding match of the 1977 All-Ireland Senior Football Championship, an inter-county Gaelic football tournament for the top teams in Ireland. The game was contested by Armagh and Dublin. Dublin retained the Sam Maguire Cup.
This was Armagh's second ever All-Ireland final. Their previous appearance was in 1953. Dublin had appeared in the previous three finals, winning two of those (1974 and 1976).
Jimmy Smyth captained Armagh.[1]
Jimmy Keaveney scored 2–6, which was the amount Dublin won by. This final's eight goals is joint most scored in a final, a record shared with the 1948 match.[2]
Joe Kernan scored two of Armagh's goals.[3]
An early goal by Keaveney and Dublin led by 3–6 to 1–3 at half-time and by 4–8 to 1–3 at one point in the second half before the two Kernan goals; in 2022, Martin Breheny listed it among "five of the worst" All-Ireland SFC finals since 1972.[4]
Armagh would not return to an All-Ireland football decider until 2002.
